The Common Core standards have not only increased the rigor for students and teachers but parents as well. I recently attended a session for parents at my children's school and there was an overwhelming cry of desperation for help with learning the strategies themselves so they can help their children. Many teachers are using number lines and base ten strategies to teach children to really understand math concepts like adding and aubtracting but parents are left confused since it's not the way they learned how to do it, often ending in conflict and frustration and even tears during homework time.
So what strategies and websites do you have to share that might address this need for parents and maybe even some teachers to learn the strategies themselves. I recently learned of Illustrative Mathematics from a teacher that uses the visual representations of the CCSS to communicate with students and parents. So share your ideas so we can all help increase our math tool kits.
